About this 3D model

This is my very last try to make it really fast. There is no way without a wide stern part. The other problem is the high bow wave which sprays water into the boat. You can avoid it by spray rails. This is not unusual on real boats. With both improvements it runs pretty well and I think it is fast enough - at least for me ;-) http://youtu.be/5ZNzgMwRtdA
